Types of Electric Actuators and Its Applications

The actuator is a mechanical or electro-mechanical device which is used to offer controlled, positioning and sometimes limited movements which are functioned manually, electrically, or by a variety of fluids like air, hydraulic, etc. The two necessary motions are rotary and linear, where linear actuators vary the power into straight line motions, normal for positioning electrical actuator applications, and generally, have two tasks namely push and pull. Some linear actuators are not power driven and functioned manually by utilizing a rotating handle or hand wheel. Rotary actuators alter energy to provide motion of rotary. The main purpose of this is the control of several valves like a butterfly or ball. For various power configurations, each kind of actuator has different versions and available in various sizes and styles based on the application. Different types of electric actuators have versions for various power configurations and come in many styles and sizes depending on the application.

Types of Electric Actuators

Basically, an electric actuator is one kind of gear motor which can be of various voltages and is the main torque producing component. To stop extreme current draw, electric actuator motors are generally set with a thermal overload sensor fixed in the motor windings. This sensor is energetic in series with the power source and unlocks the circuit should the motor be excited, then locks the circuit when the motor attains a secure operating temperature.

Types of Electric Actuators

An electric motor consists of an armature, an electrical winding, and a gear train. When power is supplied to the winding, a magnetic field is generated causing the armature to rotate. The armature will turn as long as there is a control to the windings when the power is cut, the motor discontinues. Typical end of travel limit switches, which are essential for an electric actuator, handles this mission.

These actuators rely on a gear train, which is attached straight from the motor to improve the motor torque and say the output speed of the actuator. The single way to alter the o/p speed is to fit a cycle length control module. This module lets an increase in cycle time only. If a reduction in cycle time is necessary, an alternating actuator with the preferred cycle time and correct output torque must be used.

Rotary Electric Cut Off Actuator

Rotary electric cut off actuator allows the integrated standard signal and alters the signal into equivalent angular displacement, so as to mechanically control the valve and achieve the automatic modification task. In the automatic change, the physical, mechanical and bi-directional intrusion free controlling of the regulating system can be recognized. It comprises two parts, namely actuator, and servo amplifier. It can be controlled rapidly or physically at a distance.

Linear Electric Cut Off Actuator

Linear electric cut off actuator is available with two sorts of power supply model such as AC single-phase power supply & three-phase AC power supply. The latest electric actuator is established from the regulator control signal to attain a prearranged linear reciprocating motion. This sequence of electric actuators is employed as the regulating valve actuator, almost with the control valve itself needs a range of action change function, and the opening of the electric actuator valve signal function and physical function. Thus, it is extensively used in various industries like power generation, metallurgical, papermaking, petrochemical, environmental protection and light industries.

Rotary Electric Regulating Type Actuator

This type of actuator is a full electronic actuator gets 4mA to 20mA d.c or 1V to 5Vd.c input signals from the PC, operator or regulator to work with 220V AC single phase power supply like the driving power supply, and is offered with a servo system. An extra servo amplifier is not necessary. The input component “controller” accepts the complex mixed integrated circuits, and is hardened by resin pouring & topic to aging behavior, thus being high inconsistency and opposing to vibration and moisture. When the base and crank is accepted for fitting, the location of the crank zero end can be determined randomly within 0-360℃. In addition, the electrical actuator has the overload, temperature, and torque switch safeties, is high in control precision, product high inconsistency and competent of figuring the angular travel electric regulating valve with a variety of angular travel changeable mechanisms.
